Why It Matters

Most ADU projects have four people in charge.
Yours has one.

The usual version goes like this. You hire an architect. You wait for plans. You find a contractor. The contractor tells you something in the plans will not work. You go back to the architect. Somewhere in there the city asks for a revision and nobody is quite sure whose job it is to answer.

We do it differently. We have our own architect. Your plans, your permits, and your build all run through the same office, under one license. When the city wants a change, we handle it. When something needs to be adjusted in the field, the person who drew it and the person building it are already on the same team.

If you already have approved plans, we can build from those. If you are starting from a blank lot and a rough idea, we can take it from there.

Two Ways to Add Space

Detached new construction, or a garage conversion.

Detached New Construction

A standalone unit built from the ground up in your yard. Full foundation, framing, roof, and its own utilities. You get to decide the layout, the square footage, and where it sits on the lot. This is the option when you want real separation between the main house and the new space.

Garage Conversion

Turning the garage you already have into finished living space. The structure is standing, which usually means a shorter timeline and less site work. Insulation, drywall, flooring, electrical, plumbing, windows, and a proper entry. Done right, nobody walking in can tell it used to be a garage.

Most homeowners arrive undecided. We will walk the property with you and tell you honestly which one makes sense for your lot, your setbacks, and what the city will actually approve.

How the Job Actually Runs

Four steps, one contractor

01
The Lot Conversation
We come out, walk the property, and talk through what is actually possible. Setbacks, utility access, where a unit can legally sit, and what your city tends to approve. This conversation is free and there is no obligation attached to it.
02
Design and Permits
Plans get drawn and submitted. We coordinate with the city, answer their questions, and handle revisions. You are not sitting on hold with the planning department.
03
Build
Foundation through finish, with our own crew under our license. You get a schedule before we start and you hear from us when something moves.
04
Final Inspection
The city signs off, we walk it with you, and you get the keys to a finished unit.

Most ADU projects run six to eight months from first conversation to final inspection. Plans and permits take a real portion of that. Anyone promising much faster is either skipping something or has not dealt with a California city.

Questions

ADU Construction FAQ

How long does an ADU take?
Six to eight months from the first conversation to final inspection, for most projects. Design and permitting are a real part of that and they are not something anyone can rush past the city. A garage conversion can run shorter since the structure is already there. We give you a schedule before we start and we tell you when something moves.
Do you handle the permits?
Yes, all of it. Plans, submittal, city coordination, revisions, and inspections, coordinated under CSLB #1057677. We have our own architect, so the drawings and the build come from the same office. If you already have approved plans, we can build from those instead.
Do you charge for plans?
The first conversation is free. We'll look at your lot, talk through what's possible, and tell you honestly whether an ADU makes sense there. If you decide to move forward and need plans and a detailed scope of work drawn up, that's a paid design phase, quoted upfront before any work begins, and it goes toward the cost of your build. If you already have approved plans, we can build from those.
Can I rent it out?
That is what a lot of homeowners build them for. California law has opened up considerably on ADUs in recent years, though the specifics on rentals, occupancy, and short-term versus long-term vary by city. We will tell you what your city currently allows during the lot conversation so you are planning around real rules rather than what someone heard.
How big can I build?
It depends on your lot size, your setbacks, and your city's rules. Most South Bay ADUs land somewhere between a studio and a two-bedroom. We measure the property and tell you the actual ceiling rather than a number off a website.
Does it need its own utilities?
Usually some separation, and how much depends on the city and on what the existing service can carry. Sometimes the main panel handles it. Sometimes it needs an upgrade. We check that during the lot walk rather than discovering it after the foundation is in.
Will it hurt my property taxes?
An ADU is new square footage, so it gets assessed. The existing house is not reassessed, only the addition. Talk to your county assessor for your specific numbers. We are contractors, not tax advisors, and we would rather you hear that from the right source.
Are you licensed and insured?
Yes. CSLB #1057677, active, and carrying liability coverage. Verify it on the CSLB website before you hire anyone, including us.

Not sure if an ADU works on your lot?
